CHURN.

SPECIFICATION forming part of Letters Patent No. 768,633, dated August 30, 1904.

nppncation filed August 190s.

To a/ZZ whom it may concern:

Be it known that I, WILLIAM SMITH, a citizen of the United States, residing at Springdale, in the county of Washington and State of Arkansas, have invented certain new and useful Improvements in Churns; and I dodey clare the following to be a full, clear, and exact description of the invention',such as willl en-l able others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

i My invention is a churn; and it consists of a base on which rests the churn-pail and from one end of which rises `a vertical yframe to 'f which is hinged a horizontal frame carrying two pulleys around which works a belt operated by a lever, and from one of these pulleys extends downwardly a hollow arm in whicl is secured the handleof the dasher.

The minor details of the invention are described in the specification.

The object of my invention is to produce a churn which may be cheaply manufactured and easily operated, the lid of which may be easily and quickly raised, so that the condition of the milk may be examined, and that will prevent the milk from splashing out.

In the accompanying drawings, Figure 1 isA an elevation of my invention, partly in` section, the lid down. Fig. 2 is an elevation,

partly in section, the lid up. Fig. 3 is a detail view showing the upper part of the dasher and the means by which it is secured to its pulley. Fig. 4 is a detail view showing the lever, the ends of the belt passing through a perforation and secured. Fig. 5 is a detail showing the upper end of the posts in which the lower rail of the y,horizontal frame rests. Fig. 6 is a detail view of part of the lever 17 and belt 20, showing'another means of reguserial No. 170,732. (No model.)

`beams 11 and 12 are secured one to the upper face and theother to the lower face of said block on parallel lines. "Running vertically through the ends of these beams are perforaf tions 14, the lower perfor-ations registering with the upper ones, and journaled in these perforations are pulleys 15 and 16. Hinged y to said bearingfl is a lever 17, its upper end extending some distance above the horizontal frame 10 andl bearing in said upper end a handhold 18. Said lever is made somewhat wider near its center than at each end, and

through the wide part of said lever is a per' foration 19, through which is drawn the free end of the belt 20. One end of this belt 2O is secured to the face of the lever 17 by a staple 21. Below the perforation 19 and .slightly tothe right thereof is another perforation, 22, and below the perforation 22 and slightlyto the right thereof is another perforation, 23. Fitting in one of these perforations is a pin 21. The purpose of these two or more last-mentioned perforations and pin is to regulate the tension of the'belt.

When the belt is drawn around the pulleys and its end 21 secured as shown, its other end, 25. is drawn through the perforation 19 and down straight, as indicated by the dotted line 26.` If the belt becomes a little loose, I push this end over to the right and insert the pin in the middle hole 22, and if after alittle use the belt becomes loose again I push this end of the belt over to the right beyond the hole 23 and insert the pin in said hole; but should the belt` become too tight from any cause, weather or otherwise, after having been pushed over to the last-mentioned hole 23 I remove the pin back to the left one, (hole,) or I may remove it entirely and let the belt Vresume its normal straight line 20. Thus it will be seen how quickly and easily the tension of IOO the belt'may be regulated simply by moving the pin; but should the belt stretch so much that the moving of the pin may not be sufficient to regulate its tension I loosen the staple 27 and draw the end of the belt down a little and secure it.

rlhe spindle 28 of the pulley 16, journaled over the churn-pail, has secured to its lower end a sleeve 29.

Fig. 6 shows another method of regulating the tension of the belt. In this method one end 21 of the cord is secured by a staple, and below this end of the cord are a number of perforations through the lever, one below the other, the pin 24 being adapted to iit in either one of the perforations. The free end of the cord is drawn through the perforation 19 and down around the pin 24, which is in the upper perforation, and then up, forming aloop. To tighten the'tension of the cord, I move the pin down from perforation to perforation as required.

The churn-dasher 30 consists of two perforated arms 31, the upper ends of which are secured to a body 32. Extending above the body is a neck 33, which a short distance from the body is made smaller, leaving a shoulder 34. Fitting around the smaller and upper part of the neck 35 and down against the shoulder 34 is a washer 36. rlhe upper face of this washer fits against lid 37 of the churn and keeps the milk from splashing out through the perforation in said lid. Passing horizontally through the sleeve 29 is a pin 29. The smaller part of the neck 35 has in its upper end a V-shaped depression, leaving two vertical extensions 352. The said pin 29 iits in this V-shaped depression, and consequently when the spindle 23 of the pulley 16 is revolved the neck 35 and the dasher 30 are necessarily revolved. Passing through the lower end of the sleeve 29 and the upper end of the neck 35 are perforations concentric with each other, and passing through these perforations is a Cotter-pin 38, which holds the sleeve 29 to .the neck 35.

Figs. 1 and 2 show an edge view of the righthand standard 5 of the frame 3.

Fig. 5 shows a face view of the upper end of the standard 5. In the upper end of this standard 5 is cut a slot 39, leaving a vertical spring 40. To the other edge of the standard is secured a cleat 42. This spring 40 and cleat 42 extend a little way above the standard 5, so that when the frame 10 is down the lower beam thereof rests on the upper end of said standard and is bound between said spring and said cleat. The tension of said spring 40 is regulated by a thumb-screw 41.

When I desire to examine the condition of the milk in the churn-pail, I raise the forward end of the frame 10, which brings up with the churn-lid washer and dasher, and when I let the frame down again it is clamped between said cleat and spring. To prevent the frame 10 and lid 37 from being raised too high, Yll attach one end of a strap 4C) to the standard 5 and the other end to the beam 12, so that when the frame 10 is down the said strap hangs loose in the forni of the letterS; but when said frame is up said strap is taut,

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is
